Title: Improvements in track-laying wheels for vehicles
IPC: B60B15/18
Filed: 1945-08-22
Abstract: 597,549. Track-laying wheels. SINGER, O. Aug. 22, 1945, No. 21491. [Class 79 (i)] A track-laying wheel comprises track sections hinged together and connected at intervals by links to rotating cranks, the crank axles being interconnected by gear mechanism. The track sections 10, Fig. 1, are hinged together at 11 and connected by links 12 to cranks 14 mounted on stub axles 13 carried by a freely rotatable hub disc 15, the. cranks being fast with pinions 17 which are interconnected by gear 18 keyed to axle 16. The axle 16 may be driven, or the track may be mounted on a towed vehicle. If a comparatively small number of truck elements are used, e.g., six as in Fig 1, the pinions 17 and gear wheel 18 are preferably made of irregular shape as shown, to retard the movements of the crank arms 14 which are disposed on either side. of the axle, and to accelerate the movement of those above and below the axle, in order to get a smoother action. In the form shown in Fig. 2 wherein a larger number of track sections is used the crank arms 24 are attached to circular pinions 27 mounted on a freely rotatable hub disk 25, which are geared with a circular gear 28 fast with. the axle 26. Alternatively, the gear 28.-of Fig. 2 may be dispensed with and the pinions 27 interconnected by an endless chain, which may pass round jockey wheels between each adjacent pair of pinions, the jockey wheels also being mounted on the rotatable hub disk. The irregular movement of the crank arms described with reference to Fig. 1 may be achieved with such an endless chain drive by arranging for the jockey wheels to move towards and away from the centre of the assembly at appropriate angular positions of the hub disc, e.g., under. the action of a stationary cam. The track sections 10 may be rigid or flexible and .may be faced with rubber, and the rigid links 12 may be replaced by spring links or flexible connections permanently under tension. The whole mechanism may run in an oil bath. Specification 530,969 is referred to.

Title: Method and apparatus for producing textured yarn
IPC: D02G1/08
Filed: 1972-05-09
Abstract: 1360883 Friction twisted yarn CHADBOURN Inc 9 May 1972 [8 Dec 1971] 21586/ 72 Headings DID and D1F A method of producing textured yarn on a draw-twister comprises moving the yarn along an elongated feed path and heating the yarn while in motion along the length of the path, cooling the yarn as it moves from the heating zone, then drawing the yarn across a friction surface on a freely rotatable roller the axis of which is at an acute angle to the yarn approach and causing the moving yarn to move the friction surface to twist the yarn which twist backs into the heating zone, and drawing the yarn from the friction surface along a loop path on a smaller diameter portion of the said roll, the loop path being in a plane perpendicular to the axis of rotation of the roll. The yarn 1 taken from a supply passes round feed roll 2 of the draw-twister and then passes through a heating zone 8 including a tubular heater 15, the yarn passing over the surface thereof. The direction of the yarn is changed by rolls 9 and the yarn passes through a cooling zone before contacting the friction surface of freely rotatable roll 12. The twisted yarn then passes round draw roll 5 and the drawn, textured yarn is taken-up. The roll 12 is in the form of a V-grooved or modified V- grooved roll, the yarn being first brought into contact with one side of the groove surface, then down into the bottom of the groove and then up the opposite side of the groove, while being kept in contact with the friction surface. The grooved roll may be made of metal or plastics material, polyurethane being most preferred. The groove may be in the form of a straight sided V, a concave, or convex sided V, one side of the V may be longer than the other, or in a further embodiment, the groove has a flat bottom with the sides extending perpendicularly to bottom, the outer edge of each side being convex. As the yarn moves down the groove and then up again, a decreasing and then increasing number of turns per inch is imparted to the yarn. The yarn is shown as contacting the roll 12 through 360, but this is not essential.

Title: Improvements in and relating to the production of dried potatoes
IPC: A23B7/03
Filed: 1936-08-05
Abstract: In producing dried potatoes the inner portions freed from skin and eyes are after subjection to heat treatment to destroy ferments, treated with cold water, common salt being present during the heat or the cold water treatment, and then dried by means of hot air or steam.  The waste, e.g. skins and eyes, is worked up to a durable product.  The inner portions may be treated with salted boiling water and then with unsalted cold water or may be boiled with unsalted water and then sprayed with salted cold water, the salted water which runs off being collected for use again.  The cold water may be sprayed on the potatoes as they pass from the boiler to the drier, e.g. on perforated bands or in perforated buckets.  The used cooling water may be employed to make up the level of the water in the boiler in which the heat treatment is carried out.  The drying may be effected by a circulating stream of air, the initial temperature of which is 90 DEG  C. or less, the temperature being gradually reduced as the removal of moisture proceeds.  A stage drier may be employed in which, for example, the initial temperature is 90 DEG  C.; when the temperature falls, say, to 80 DEG  it is raised to about 85 DEG when it has fallen to, say, 75 DEG  it is raised to 80 DEG ; and so on.  The heating of the air for drying may be effected by heating bodies operating with low pressure steam.  The drying may also be effected by conveying the inner portions on carriages or on a belt conveyer through a tunnel against a stream of hot air or superheated steam.  The waste material may be subdivided and then further worked up; for example, the skins, which have been removed from the potatoes by grating, the eyes and the bad parts are grated in a potato grater, and pressed to remove the juice from which the sinking and floating parts still therein are separated in a settling vessel and returned to the press.  The skins may be sent direct to this settling vessel. The solids from the press are dried, e.g. on drum driers, higher temperatures than with the inner portions being used.  The sludge from the settling vessel may be supplied directly to the drier or sent to the press.
